How do I install itunes not to write a value to a key

This prompt appears: Unable to write the value to the key Softwaremicrosoftwindowscurrentversionexplorerautoplayhandlerscancelautoplayclsid. Verify that you have sufficient access to the key, or contact your technical support personnel.

Although I click "Ignore" three times in a row, the installation will still be done, and itunes will be able to open after the completion, using the normal (maybe I did not use it to install the wrong features ...?)

Reason Analysis:

There is no permission to write to the registry, it should be that the user of Windows you enter is not an administrator or the registry is locked by the software

Workaround:

It is recommended that you start Setup as an administrator (right-click on the installer, and then choose to open as an administrator, OK.) ) and, in addition, to completely uninstall the previous old version. And then we'll install the newest one.
